[POWERPC] pci32: Add flags modifying the PCI code behaviour
This adds to the 32 bits PCI code some flags, replacing the old pci_assign_all_busses global, that allow us to control various aspects of the PCI probing, such as whether to re-assign all resources or not, or to not try to assign anything at all. This also adds the flag x86 already has to avoid ISA alignment on bridges that don't have ISA forwarding enabled (no legacy devices on the top level bus) and sets it for PowerMacs.
